Trackpad click on a certain image as a trigger

Actually, this is NOT strictly true. You can trigger on a click by using the USB Device Key trigger (KM Wiki).
I do NOT recommend using this method, because a mouse click is one of the most common events on your Mac.

But, if you really want to use a click to trigger your macro, here is an example.
